<P>PROBLEM TO BE SOLVED: To provide a ceramic honeycomb structure constituted so that a faulty part generated on the outer wall of this structure can be repaired surely without deteriorating the mechanical strength and thermal impact resistance of this structure and that a liquid leaks to the outer wall at a catalyzing step can be eliminated. <P>SOLUTION: This ceramic honeycomb structure has many flow passages divided by many partition walls and the outer wall for dividing the flow passages from the outside. At least one or more faulty parts being openings are filled/plugged with a ceramic material, which are generated on the surface of the outer wall and each of which has ≥0.1 mm width and is communicated with the flow passages. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
